BUBBLE PRODUCING MACHINE Flled Sept 12 1951 March 24, 1953 Patented Mar. 24, 1953 UNITED STATES PATENT OFFICE Claims.

This invention relates generally to a bubble producing machine, and more particularly to a machine for producing multiple continuous streams of bubbles which are blown upwardly.

Bubble producing machines of the aforementioned type have many uses and adaptations. Such machines may be used as amusement devices, and are particularly appealing to young children. In addition, such machines are readily adapted to use for advertising purposes. For example, the bubble producing machine of the instant invention can be enclosed within an enlarged replica of a drinking glass or the like, and made to simulate an effervescent beverage. Other uses and adaptations will become apparent upon an understanding of the instant invention.

Accordingly, it is an object of the instant invention to provide a bubble producing machine arranged to produce one or more continuous streams of bubbles.

In addition, it is an object of this invention to provide a bubble producing machine arranged to produce a continuous stream of bubbles which are blown upwardly either in a vertical or a diagonal direction.

Another object of the instant invention is to provide a bubble producing machine wherein a plurality of loop means are moved through a container filled with film-forming liquid and then past a blower means whereby to produce a stream of bubbles which are blown upwardly.

It is also an object of the instant invention to provide means for removing excess liquid from the loop means and returning it to the liquid container prior to the passage of air through said loop means to form a bubble.

Another object of the instant invention is to provide a bubble producing machine having the aforesaid characteristics and which is inexpensive to manufacture, simple in construction, and reliable in operation.

These and other objects of the instant invention will become apparent upon reading the ensuing detailed description thereof taken together with the accompanyingdrawings wherein:

Fig. 1 is a top plan view of the instant invention with parts broken away for greater clarity.

Fig. 2 is a side view in section taken along line IIII of Fig. 1;

Fig. 3 is a view in side elevation, and with certain parts in section, taken at a right angle to the view of Fig. 2; and

Fig. 4 is a fragmentary detail view of one of the loop means of the instant invention.

Referring now to the accompanying drawing,

the instant invention is seen to comprise a base I to which is secured in any known manner an inverted U-shaped support member 2. Support 2 is centrally apertured, as at 3, and a sleeve 4 is secured therein, as by welding. A bearing member 5 is carried within sleeve 4, and a shaft 6 is rotatably journaled within said bearing member.

At its outer end shaft 6 is provided with a reduced portion 1 on which is mounted a hub member 8. Member 8 is fixedly secured against rotation on portion 1 of shaft 6by any conventional means, such as a key, and is held in place thereon by a nut 9. At its inner end, shaft 6 fixedly carries a driven drum I0, and a drive cable I I extends around drum H) to any-suitable driving means, not illustrated. A spring member 8 extends between hub member 8 and support 2, being fitted around shaft 6, and serves to maintain hub member 8 in proper spaced relation with support 2 without interfering with the rotation of hub member 8. If desired, other spacing means can be used for this purpose.

A plurality of loop members l2 are secured to hub member 8, being carried at the outer end of slender arms l3 which are secured at their inner ends to said hub member in any conventional manner. Arms [3 are shown as extending outwardly and downwardly to loop members I2, but other shapes can be utilized if desired. At a point between loop members l2 and the point of attachment of arms I 3 to hub member 8,-a tension spring member l4 extends between each of said arms and said hub member, whereby after downward deflection of said arms and said loop members for a purpose to become apparent, said springs M will restore said arms and loop members to their normal position. Alternatively, arms I3 can be made sufficiently resilient in themselves so that springs [4 can be dispensedwith. As shown in Fig. 1, loop members l2 form a circle around shaft 6 in plan view.

Two trough-like containers l5 and I6 for filmforming liquid are mounted on the upper side portions of support 2. Any suitable bubble or film-forming medium can be used. Said containers extend in an arcuate direction to coincide in plan view with said loop members, and in the particular embodiment herein illustrated, said containers l5 and I6 together extend beneath most of said loop members. Said container are spaced beneath the normal level of said loop members. Bracket members I! and I8 extend outwardly from support 2 and around and over containers l5 and I6, respectively, and carry at their upper ends cam-shaped deflecting members Means are'provided for directing a stream of air upwardly through the liquid-laden loop members, and said means are shown to include duct means 2| and 22, which duct means extend upwardly from base I to the spaces between con tainers l5 and I6. At their lower ends, duct members 2! and 22 connect to a conduit 23 which is arranged for connection to suitable blower means, not illustrated. Thus, after said. loop.

members l2 pass beneathdeflecting members I9 and 20 to pick up film-forming liquid, they pass over ducts 2| and 22 and the upwardly directed streams of air pass therethrough to form bubbles which are blown upwardly. v

Means for removing excess liquid from said loop members are provided intermediate deflecting members I9 and 20 and ducts 2| and 22, respectively, and comprise scraper members 24 and 25 which members are mounted on springs 26 within containers I5 and I6, respectively, as illustrated in Figs. 1 and 4. The top of each of said scraper members is arranged to bear against the bottom of loop members 12 as they pass thereover, whereby any excess liquid is removed from said loop members and returned to said containers. In this way, waste of the liquid medium incontainers I5 and I6 is prevented. Also, the spring mountingof said scraper members insures that they will accommodate themselves to variations in the height or level of said loop members.

To summarize the operation of the instant invention, cable II is driven to drive drum l and hub member 8 in the direction shown by the arrow in Fig. 1. Loop members I2 are thereby rotated, and, as they pass deflecting members 19 and 20, they are depressed into the liquid in containers I and I6, respectively. Said loops then pass over scrapers 24 and 25, respectively, whereby any excess liquid is removed from said loop members, and they then pass over ducts 2| and 22, respectively, whereby bubbles are formed and blown upwardly by the upwardly directed streams of air.

Thus, the instant invention fully accomplishes its aforesaid objects, and provides a bubble producing machine which produces plural continuous streams of bubbles which are blown upwardly.

Obviously, the instant invention is susceptible of many modifications and is not to be limited to the specific details of construction disclosed herein. Thus, the number of air ducts and containers can be varied to vary the number of streams of bubbles which are produced, and changes can be made in the various component parts, all without departing from the inventive concept, and it is intended that the instant invention shall be limited solely by the scope of the appended claims.
